Deep negative pressure drainage flusher

Abstract

The invention discloses a deep negative pressure drainage flusher, and belongs to the technical field of medical instruments. The deep negative pressure drainage flusher is characterized by comprisinga flexible tubular body, the front end of the tubular body is closed, and an opening is formed in the rear end of the tubular body; a plurality of through holes are formed in the tube wall of the tubular body, and the tubular body is spirally wound into a screw-shaped structure with a cavity in the middle. The flusher is simple in structure, ingenious in structural design and easy to operate, drainage and flushing of deep tissue of an affected part can be achieved, and the treatment effects of negative pressure drainage and flushing are improved.

Description

technical field [0001] The invention relates to a deep negative pressure drainage washer, which belongs to the technical field of medical instruments. Background technique [0002] Diabetes mellitus is a lifelong metabolic disease characterized by chronic hyperglycemia caused by multiple etiologies. Due to peripheral neuropathy and peripheral vascular disease combined with excessive mechanical pressure in diabetic patients, many complications can be caused. In severe cases, patients are prone to ulcers on limbs, trunk and other parts, especially the lower limbs and feet at the end of blood circulation more prone to ulceration. When an ulcer occurs in a patient's limb, during the treatment process, it is usually necessary to decompress and drain the affected part through negative pressure suction to help the affected part heal. In the prior art, when negative pressure treatment is performed on the affected part, the affected part of the patient is generally wrapped up, and ...

AI Technical Summary

Problems solved by technology

This method is better for the treatment of shallow ulcers, but it is difficult to achieve effective treatment for deep ulcers.

Moreover, when the drainage tube in the prior art is used to perform negative pressure drainage on the deep tissue of the patient, it is easy to block the tube and cause poor drainage, or the granulation tissue in the affected part is easy to grow into the drainage tube to block the drainage tube, resulting in ineffective drainage. drainage

In addition, in the prior art, a good therapeutic effect can be achieved by irrigating the superficial ulcer surface, but the irrigating method cannot be used for the treatment of deep ulcers.
